The Active Control Program For Advanced UV Oxidation

Advanced Oxidation Processes (AOP) that combine UV light with oxidants like hydrogen peroxide or chlorine are vital for treating persistent micropollutants, especially in regions facing water shortages or contamination. However, the efficiency of UV AOP systems can be significantly affected by changing water characteristics such as UV transmittance, pH, alkalinity, and nitrate levels.

To ensure compliant contaminant removal while managing operating expenses, control programs must dynamically adjust UV intensity and oxidant concentration. Simple fixed-dose strategies risk under-treatment when water quality worsens. An alternative, active control approach, automatically calculates and adjusts UV and oxidant dose targets in real time based on monitored water chemistry data. This allows the system to maintain guaranteed treatment performance while encouraging more economic operation if conditions improve, even balancing against fluctuations in electricity and chemical costs.
